2009:

Dimitri sustained a tragic accident at home while working on
his roof, unsecured.. Fell 15 feet on a concrete floor. Back surgery: split L1
lombar vertebrae and relate joint were successfully fused with T12 and L2
vertebrae with the help of 6 titanium screws and wire, therefore avoiding
potential paralysis.

Consequently, Dimitri was forced to take a year of
convalescence, wearing a "turtle shell" for the first three
months,and reflecting on Kafka's
"The Metamorphosis"

Followed intense physical therapy, travelled in europe,
hiked the GR20 in Corsica, rode a motorcycle through the continent and met
Gulnara Miftakhova while visiting friends in Morocco.

First skiing, then trekking with a backpack and pulling the sled simultaneously then
finally swimming and/or using the sled as a kayak while going down
remote Chukotkan rivers. Encountered
numerous grizzly bears but no humans in a 30 days timeframe!

Late Fall: Returned to Vayegi! Started too early in the season: rivers were not yet solidly frozen,
had a limited amount hours of daylight,
equipment failure. Therefore aborted after one week and decided to come back in
the winter.

2007:

Return in Russia! Trekked and skied 685 kilometers (425
miles) from Uelen to Egvekinot through
desolate Chukotkan tundra with Karl Bushby. Reflecting on the Bering Strait,
the history of civilization and species migration and recognition from Seattle
Metropolitan Magazine...

Completed Bering Strait Crossing successfully in 322 kilometers (200 miles) with Karl
Bushby, trekking, skiing and swimming from one ice surge to the next, among spotted seals and polar bears. First
Eastbound crossing completed in modern times. Recognition from National
Geographic, and Seattle declares June 23rd 'Dimitri Kieffer Day'...

2005:

Nexus Expeditions began in February of 2005 at Knik Lake in
Alaska. Dimitri Kieffer competed in the Iditarod Invitational Race, traveling
1,770 kilometers (1,100 miles) in 37 days by foot and snowshoe from Knik Lake
(near Anchorage) to Nome. He was the 6th person to ever finish this race by
foot since the race started in 1989, following the trail of the infamous
Iditarod dog race.

As a surprise, his father, Henri, met him near the village
of Solomon after flying all the way from France and having travelled on a
snowmobile to surprise him.

During the course of the race, Dimitri met Karl Bushy and together they spent the rest
of the year for their 2006 Bering Strait crossing.

From this beginning, Dimitri would embark on a human-powered
journey to circumnavigate the world.

In April 2008, Dimitri continued his expedition solo, in Chukotka, Russia, starting in Egvekinot where he had last stopped and covered 600 miles.

He completed this section by foot and skis while pulling a sled along the Siberian coast and river beds. As the spring advanced and the snow started to rapidly melt, Dimitri had to trek some of the last hundred miles with a backpack and pulling the sled simultaneously, swimming, and finally using the sled as a kayak and a shovel as a paddle while going down rivers.

In March 2010, Dimitri returned to the village of Vayegi and continued by foot and skis while pulling a sled moving Southwest towards Kamchatka. He completed the first month in company of Yakut trekker Nyurgun Efremov who stopped in the village of Slautnoye, Kamchatka.

From there on, Dimitri completed the next 200 kms in company of three beautiful roaming dogs and reach Kamenskoye. After having left the 3 canines in good company, he continued solo, mostly following the coastline where he could still find barely enough ice to slide his sled on, swimming and backpacking along the way and was finally able to reach the remote koryak fishing village of Paren.

Dimitri was also enthused to be able to meet and stay for a few days along the way with two different "brigades" of reindeer herders, a chukchi one and a koryak one where he was able to learn about and appreciate their nomadic culture.
